(1) Frame 9 and Frame 10 drives require two or three parallel reactors to match drive amp rating. The resistor ratings are per phase values for each reactor.
(2) Resistor specification is based on two parallel cables per phase.
(3) Resistor specification is based on three parallel cables per phase.
(4) Resistor specification is based on four parallel cables per phase.
(5) Resistor specification is based on five parallel cables per phase.
(6) Resistor specification is based on six parallel cables per phase.
